Since the guitar is a transposing instrument, sounding one octave lower than 
written, I tend to think one should be able to either enter the written pitches 
with the MIDI sounding one octave lower, or enter the pitches as sounded, 
written one octave higher.

The LilyPond \transposition does the former, but the second might be useful if 
changing the instrument.

Re: Clef "treble_8"

Hi Michael and Karlin,

thank you for your positive reaction. There are 3 files¹:

- a cheat sheet: https://joramberger.de/files/lilypond_sheet_2.18_en.pdf
- “visual index”: https://joramberger.de/files/lilypond_visualindex.pdf
- spacing overview: https://joramberger.de/files/LilypondSpacing.pdf

The cheat sheet is also available in other languages (and as SVG)²:

https://joramberger.de/files/lilypond_sheet_2.18_de.pdf
https://joramberger.de/files/lilypond_sheet_2.18_fr.pdf

https://joramberger.de/files/lilypond_sheet_2.18_it.svg


>> Why isn't this part of the official docs?

I once tried to get them in an appropriate place in the official
documentation. But they were not accepted. For the cheat sheet, main
objections were:

- not source code (even though SVG is an open and text based format)
- needs updates for new versions (well, those basic things did not
  change for at least 7 years now and even if they did…)
- does not fit into the texinfo documentation creation process (ok)

The case of the spacing overview is similar. The visual index is created
from a LilyPond source code. If I (or someone) finds a way to create a
clickable SVG file from it, one could include it into HTML and make it
blend much better into the/a documentation website.

That was my reaction, too. Plus, there's at least one more work like it:



I'm usually not a very demanding LilyPond user. I have trouble staying 
sharp on all the different spacing and padding settings, due to not 
using them much. As a result, I've learned to like that Spacing map a lot.

In the description or probably as a comment in the code.

Nope. My experiments with 'with-output-to-string' weren't successful,
at least for ly:warning and similar.
Ofcourse one could avoid ly:warning and go for some other printing
function, but I think it would lead to more confusion instead of
helping the user.

you can basically \omit anything as soon as you know what the object it

something wrong :
\version "2.18.2"
\score
{
\new Staff {
   %\clef "treble_8"
\transposition c''
   b
 }
}

Now I want also the time signature "C" to disappear... I've read the doc

but don't see how. Is there a "\omit" ?
Thank you for your responses

I'm surprised that the "include..." line was missing in your templates. AFAIK

about ten years ago.


I hope the extension will be useful for you. Some new features are coming

Author: Thomas Morley 
Date:   Fri Jul 28 23:09:14 2017 +0200

Issue 5168 Let arpeggio-bracket/slur depend on grob-property thickness

Before, used thickness based only on line-thickness from layout.
For brackets it's now the multiplication of line-thickness and grob's
thickness.
Slur-style-arpeggios now rely on grob-properties thickness and
line-thickness, both multiplies with layout line-thickness.
Similiar to real Slurs.

Will likely be available in 2.21.0 or from current master.

For now you'll need to self-compile LilyPond from master or recreate
the stencil.

Re: LSR contribution

[Michael Käppler]

Hi Harm,


Fine with me, I already updated the LSR-code, for now unapproved.
Please have a look whether all is ok, snippet-description and the like.

Thank you for updating!
Will update the description this evening.
Do you have any idea how to preserve indentation within  blocks?
Inserting   or the like seems hacky, inline-css-styling too...


Probably one suggestion:
How about gving the user some hint or example-message what can be
expected if warnings are triggered or debug-mode is enabled?

Do you mean inside the description or as snippet output?
Btw, do you know a way to dump warning-messages to the graphical output?

Cheers,
Michael
